Born Franklin Carlton Feranna in December 1958, he was abandoned by his father and raised by his farming grandparents. As a teen, he took off for Hollywood and lived with his aunt and his uncle, who was the president of Capitol Records.
After a series of dead-end jobs he joined Blackie Lawless' band Sister before forming his own group, London, which morphed into Motley Crue.
"You've heard the tales of excess and debauchery," Sixx says. "All the peaks and the valleys that came with rock and roll stardom and my life in one of the world's biggest bands. This is the story that you haven't heard. The one that led up to those stories."
"It's the intimate, personal story of how an innocent Idaho farm boy with a burning dream and desire - for music, for love, and for fame - became the notorious Nikki Sixx. I believe our first 21 years have a lot to do with shaping who we become. These are my first 21, and it's my hope that they thrill and inspire you to invest in your own, biggest dreams."
Speaking about the memoir, publisher Mary Ann Naples says, "Whether you're a Motley Crue and Nikki Sixx fan or not, if you're looking for a memoir that transports you back to the '70s and early '80s, and that, for those who lived it, will reacquaint you with the vinyl collection your parents threw out in the '90s, then this is your book. And the larger themes of getting to know who you are and taking control of your identity certainly resonate now in the still-new 2020s."
The new book will be available in October.
